General Description

High-Purity Water solvents are specifically formulated for PFAS (Per- and Polyfluoroalkyl Substances) testing, catering to the rigorous demands of environmental and analytical laboratories. These solvents help minimize background interference, ensuring accurate and reliable detection of PFAS compounds.

By strictly adhering to the EPA 533 and EPA 537.1 drinking water testing methods, LiChrosolv® solvents guarantee that no PFAS compounds exceed regulatory limit values. This ensures precise identification and quantification of PFAS analytes while eliminating false positives and false negatives in LC-MS/MS (Liquid Chromatography-Mass Spectrometry) analysis.

Laboratories conducting UHPLC-MS and LC-MS instrumental analysis can rely on these high-purity solvents to enhance analytical accuracy and consistency.

Application of High-Purity Water

LiChrosolv® PFAS-tested solvents are extensively used in drinking water analysis, specifically meeting the requirements of EPA 533 and EPA 537.1 testing methods. These solvents provide:

• Ultra-low PFAS contamination, enabling trace-level detection
• Consistent quality assurance across multiple batches, ensuring repeatable results in PFAS testing

PFAS Testing Features of High-Purity Water

• QC batch-tested for 29 PFAS analytes, including:
  • EPA 533: 25 analytes
  • EPA 537.1: 18 analytes
• Lot-to-lot consistency, validated by both:
  • Third-party accredited testing laboratories
  • Internal quality control laboratories

Features and Benefits of High-Purity Water

• Ultra-low background contamination:
  • Electrospray Ionization (ESI)/Atmospheric Pressure Chemical Ionization (APCI) Positive Mode: <2 ppb
  • ESI/APCI Negative Mode: <10 ppb
• Minimal impurity profile: Ensures an interference-free baseline for accurate PFAS analysis
• Borosilicate glass bottles: Prevent contamination from metal ions, maintaining sample integrity
• Exceptionally low trace metal levels (<5 ppb): Minimizes metal ion adduct formation, reducing unwanted interactions during analysis
• Advanced filtration: Solvents undergo microfiltration through a 0.2 µm filter, ensuring ultra-high purity
